rurvnnrzen.

To all whom it may concern;

Be it known that I, Mnrron J; WILLIAMs,

' a citizen of the United States, residing at Chicago, Illinois, haveinvented a certain new and useful Improvement in Pulverizers, of whichthe following is a full, clear, and exact description, such as willenable others skilled in the art to which-it appertains to make and usethe same, reference being had to the accompanying drawings, forming partof this specification, in which- Figure 1 is a vertical sectional Viewthrough a pulverize'r constructed according to my improvement; Fig. 2 isa horizontal fragmentary sectional view through the same. Fig. 3 is adetailed view of one of the disks which carry the hammer supports.

This invention relates to a new and useful improvement in pulverizers ofthat type commercially known as the Williams mills, characterized by thepivoted revolving hammers which act upon the material as it enters themachine at the hopper or feed end thereof, crushing said material as itrests upon the bottom of the hopper, or breaker plate, as it issometimes called, the material being further disintegrated or crushed bythe hammers acting thereon as the material is carried over the cage orgrinding surface. The crushed material falls through the openings' inthe cage or grinding surface into a suitable receptacle located beneaththe machine. The hammers or beater-s which revolve about the shaft,while made of amaterial whose resistance to wear is its essentialquality, will, in time, wear away at their striking ends, and thefarther these striking ends are removed from the breaker plate andgrinding surface, the less becomes the capacity of the machine.

It is the purpose of my present invention to provide means whereby theserevolving hammers or heaters may be adjusted outwardly to take up thiswear (or inwardly, ifoccasion requires, as when a new cage is introducedto replace a worn one), said means consisting of hammer supportspivotallymounted upon disks arranged upon a shaft, the inner ends ofsaid hammersupports being curved to cooperate with rods which aremounted in rotatable disks whereby the hammers may be snnultaneousl anduniformly adjusted, outwardly ant inwardly, with respect to the shaft.

cage,and 4 the cover of the machine, which may or may not be hung, asdesired.

5 indicates a shaft and 6 disks fixed which are seated circular heads ofadjusting bolts 13.- These adjusting bolts pass through.

threaded ears 14; on the disks 6 and are provided with suitable beads bywhich they may be rotated to adjustthe disks 11. t

In operation, when the hammers are new, the hammer supports aretangentially disposed as shown in Fig. 1. As they wear, the disks 11 arecircumferentially adjusted so as to bring the hammer supports nearer toa radial position, these adjustments being continued, from time to time,until the hammer supports are radial, when no further outward adjustmentcan be efiected.

I am aware that minor changes in the construction, arrangement andcombination of the several parts of my device can be made andsubstituted for those herein shown and described without in the leastdeparting from the nature and principle, of my invenclaims, I wish tobe'understood as not confining myself to circular disks, as the partswhich erform the functions of the sup orb-- ing dis rs described andclaimed could e in the shape of spildebarms, or other forms, metal beingcut a way at various places where it was not needed, to lighten themachine.

Having thus described my invention, what I claim is:

1. In a pulverizer, the combination \vitha casing, of a shaft, disksmounted upon said shaft, hammer supports pivotally arranged between saiddisks, hammers carried by said supports, means cooperating with theinner ends of said hammer supports for adjusting the hammers outwardly,a rotatable disk in the breaker plate, 3 the grinding surface or I whichsaid adjusting means is mounted, anda threaded connection between saidfixed and movable disks whereby the latter may be adjusted.

2. In a pulverizer, the combination with a casing, a shaft mountedtherein, disks mounted on said shaft, hammers supported by said disks,and means for adjusting'said hammers outwardly, said means comprisingcircumferentially adjustable rods, rotatable disks in which said rodsare mounted and a threaded rod connecting the fixed and niovable diskswhereby thelatter may be par-' tially rotated to circumferentiallyadjust said rods.

In testimony whereof I hereunto avflix my 15 signature in the presenceof two witnesses, this 8th day of February, 1909.
